BAG.

Be it known that I, ADELMER a citizen of the Unitedstates, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Bags, of which the.

following is a specification.

My invention relates to valve bags, and has for its object to provide a handlewhereby said bags may be manipulated. before they are filled during the process of filling, or after they are filled.

It is.illustrated in the accompanying drawings, wherein I Figure 1- is a plan view of a collapsed paper 'valve bag containing. my invention with parts shown in dotted lines. Fig. 2

is a longitudinal sect-ion through similar filled bags.

Fig. 3 is an' enlarged detail view of a bag end showing the handle por tion twisted. Fig. 4 is an enlarged detail view of a handle separate from the'bag. Fig. 5 is an enlarged detail view ofa modification of the handle, and Fig. 6 isasimi 'lar view of still further modifications' Like parts are indicated with the same letter in all the figures. f y

A, A are the sides of a paper "alve bag which has ends B, C, formed by properly folding the bag portions. One of these ends 7 is folded so as to leave an open valve aper- 'ture D at one edge of the bag.

E is the interior portion of the handle consisting preferably of a piece of wood of any desired shape, length or cross section on the pointed orxbeveled ends G, G.

H is the exterior handle portion of any desired shape or material.

The two parts are connected together by a portion which passes through the material of the bag. J is the exterior portion and as it is shown in Figs. 1, 2, 3, and 4, it consists of flexible cord or rope with the ends J J ,'which pass through the fabric and are made fast to the inner portion E. Where metal is used, this securing part may take the shape ofa. staple head of which J 2 lies uponthe wooden exterior handle portion H through which the legs of the staple pass. They are twisted at L, the two ends K, K passing through the fabric of, the bag and being made fast to the inner handle portionE. The upper edge of the inner handle portion E may be flat as indicated at F.

M is a staple. This may be employed to secure together the inner and outer handle portions when both are of wood. Such a' handle may be applied to any kind of a bag which is normally in a closed condition. Such a bag is my valve bag, and. here a convenient way of attaching the handle is to insert the inner portion of the handle after the bag is finished through the bag opening, and then place the flexible handle portion in position, its ends passing through the bag body, and then fastening these ends to the interior handle part.

I do not wish'tobe limited in any particular way to employ the handle, nor to the time when it. is applied. If two 'wooden parts are to be used, the inner portion should be inserted through the valve opening by a kind of carrier or mandrel, and the staple can then be driven in place through the fabric of the bag in such way as to be clenched in the inner handle piece. In Fig. 6 I have shown anail M employed in lieu of the metal staple. The handle in such a case, andperhaps in any case, is preferably placed at one side of the end of the bag,- or near the side of the bag so that it will lie at one side of the valve channel. This will permit the introduction of the valve filling tube, without its being interfered with by the handle portion. It willalso cause the handle portion to lie in such way that, if it be of wood, it will not injure the neXt adjacent bag in the pile, and in any event it will rise so that it can easily be grasped by the hand.

I desire to have my drawings taken as diagrammatic,- but -T do not wish to be limited to the particular form, size, shape and proportions of the several parts, as all these may be greatly changed without departing from the spirit of myinventipn. The use and operation ofmy invention are as follows :Whenvalve bags are employed they are filled by means of a valve filling tube which enters the valve and is withdrawn after the bag \is filled. The

-weight of the'material within the bag seats the 'valve. Such a bag in its usual form is practically without any handle attachment.

The cars of an ordinary flour sack due to the sewingprocess are absent, and so also is the gathered end of the bag which is formed when ordinary bags are tied. Since many persons are accustomed to grasping presents a long ech projecting handling are In supply some. ki

bag so that when the bag is filled and laid on its proper side, say with the brand up, the handle will be near the upper surface of the bag and thus will lie against the upperv portion of the next adjacent bag so that as the bags are manipulated to and from the pile on which they are being stacked, the handle will always be easily available.

In the case of valve bags it is usually necessary to subject them in the process of larly with or without those above suggested,-

so as to shake it or it for the purpose of settling or packing the material within the bag. A handle in the case of a valve bag thus becomes an important feature of construction for the purpose of manipulating the bag by hand or by machinery before it is filled or during the filling process or afterward.

Since the valve bag is filled from the upper end the valve being placed at'the upper end, it is highly important that the handle should be placed at or near the upper or valve end of the bag, although of course it could be placed at the other end.- Two such handles at opposite ends could be used if desired, particularly in the case of valve bags.

In the preferred 'form of my device the handle is applied to the valve bag after the bag has been otherwise finished.

It will be understood that the handle is placed in the bag after the bag has been completed. After these paper bags are delivered, for inserting the handle in a oollapsed position, it is necessary to force the inner handle portion into the bag through the valve opening. The pointed end makes this easily possible without danger of tearing the bag or jamming or twisting the It is preferably placed as illustrated in the drawings at one side of the end of the After the handle pic/ l the is ready to be ii less blunt filling tube is t e opening, and since the e handle piece is also pointed off or is guided offfrom the fill g 1, and there is no possibility of the end of the tube and the ,end of the handle piece coming into too abrupt contact with one another, such as might result in the tearing of the bag or in the stopping of the more ment of the bag on to the filling tube. The load, as the bag is carried by the handle, of course primarily applied at the center,

and experience shows that the pointed ends valve end, said handle being made up of a hand engaging member and an inner anchoring member therefor located within the bag in line with the valve, said member being pointed at one end, said point being adjacent the one side of the member and adjacent the side wall of the bag to guide a filling tube as it enters through the valve gradually along one side of the member.
